"Green" move mine -- A snapshot of ecological civilization construction in China's mining industry

Over the past 10 years, in the green mine construction, China has effectively promoted the green mine construction through a number of measures such as government-led, enterprise main, planning first, orderly promotion, typical driving, demonstration, comprehensive policy, and joint reinforcement, and gradually explored the formation of different characteristics of the experience and mode. There emerged a green mine construction model in the high cold region represented by Qinghai Duran Jinhui Mining, a green mine construction model of sand and aggregate represented by Huzhou Xinkaiyuan Gravel Co., LTD., a green mine construction model of mine land integration and ecological restoration integrated by Guangdong Shunxing Stone Yard. The green mine construction mode led by intelligent mining is represented by Hubei Sanning Mining, the green mine construction mode of unmanned and intelligent mining is represented by Luomou Group in open pit mining, and the intelligent green mine construction mode of the whole process of open pit mining is represented by the grand blasting project.

Through these years of exploration and practice, China's green mine construction has undergone a qualitative fission, and has achieved a fundamental transformation from "I want to build" to "I want to build", from "pilot exploration" to "comprehensive promotion", from "administrative promotion" to "standard guidance", from "enterprise self-discipline" to "social supervision", from "initiative guidance" to "incentive and constraint". Green mine and green mining have become a beautiful landscape in the construction of ecological civilization in our country.

Resource conservation is rich in connotation

For the construction of green mine, not only need the appearance level, to make the mine area into a beautiful park; More connotation is needed to build the mine into a typical of resource conservation and comprehensive utilization.

"The conservation and comprehensive utilization of mineral resources is the greatest protection of resources and the best care for the ecological environment." In March this year, the mineral resources development and utilization level survey and evaluation of the expansion of the pilot work and business training meeting held in Beijing, the head of the mining protection Department of the Ministry of Natural Resources said.

As we all know, improving the level of development and utilization of mineral resources and comprehensive utilization efficiency can reduce the amount of raw ore from the source and protect the ecological environment. This is also one of the reasons for green mines and an inevitable requirement for the high-quality development of the mining industry.

Over the years, the Ministry of Natural Resources has always put resource conservation in the first place, and has improved the level of resource conservation and comprehensive utilization by formulating the "three rates" index of mineral resources and releasing advanced and applicable technologies of mineral resources. In the process of building green mines, many mining enterprises rely on scientific and technological innovation, promote advanced equipment and technology, and achieve connotative development.

Relying on independent technology, Jinhui Mining Co., Ltd. puts "not only to change the mining development mode, but also to change people's views on traditional mines;  They adopted the upward slicing filling mining method, up to the domestic advanced level, can achieve selective mining, loss rate reduced to less than 8%, depletion rate reduced to less than 10%; The potential controlled flotation process of lead-zinc sulfide ore has effectively improved metal recovery and product quality, and the comprehensive recovery rates of lead, zinc and silver are up to 92.2%, 95.65% and 90.26%, respectively, which is in the leading level in China. The comprehensive utilization rate of tailings can reach 60%, reaching the advanced level in the industry, opening up a green mining development road that integrates mine production and construction with ecological environmental protection.

"The basic mineral situation of our country with poor mineral resource endowment conditions determines that we must take the innovative road of saving and comprehensive utilization." Only by continuously improving the comprehensive utilization level and efficiency of mineral resources, maximizing the use of resources, making good use of resources, and making full use of resources can we meet the requirements of high-quality development and ensure the security of the national economy." Industry analysts said.

In fact, in recent years, China has made remarkable achievements in the conservation and comprehensive utilization of mineral resources. Many mining enterprises in the green mine construction, to save resources as the goal, vigorously promote green environmental protection intelligent equipment, mineral resources utilization level and efficiency has been significantly improved, many indicators in the world's leading position, to achieve the appearance level and connotation of organic unity, not only improve the quality of green mine construction, but also build a solid foundation for high-quality development.
